What you're seeing is a flap that protrudes into the exit area! Some say it's for EGR equipped cars as it may keep exhaust flow from traveling down that path and others have said that it helps to spool the turbo up however when it's removed your turbo will actually spool a tiny bit faster! Anyway Saab quit doing this in '91, also '90 SPG's didn't have it either. Best way to remove it is to drill a series of small hole near the base of the flap, break it off and then grind that area smooth. Hope this helps, Dave
